GO terms associated with energy consumption (Figure 5A), energy derivation by oxidation (Figure 5C), and pathway influenza infection (Supplementary Figure 3C) were positively enriched in ACE2+ CM1&4; GO terms associated with energy consumption, mitochondrial envelope (Figure 5D), and pathway respiratory electron transport (Supplementary Figure 3D) were positively enriched in CM2&3. This evidence concerns the gene ACE2 and influenza.
